Please note that external pipe diameters may vary between different manufacturers and systems, and ambient temperature also affects dimensions. Please select the collar size most appropriate for your application, allowing a small clearance for ease of fitting. A close fitting between the collar and the pipe surface should be the aim, but the collar should not be unduly strained in order to close it around the pipe. A fireproof sponge filler strip can be provided upon request for special applications. Please enquire with details of your application for technical advice.
